enable power management ipw3495 on ThinkPad T60 Ubuntu 7.10

Hi,
I have a ThinkPad T60, with Ubuntu 7.10.

The fan is running close to permanently.

It is suggested that by enabling the ipw3945 power management,
it only runs about 1/3 of the time.
(See http://www.thinkwiki.org/wiki/Instal...igured_by_hand)

I tried to enable the power management with
'iwpriv eth1 set_power 7' which seemed to have
some positive effect.(See ipw3945 README for details:
http://ipw3945.sourceforge.net/README.ipw3945)

But how should I go about to make this setting permanent
(that is automatically set when the operating system is started)?

Any help is appreciated,
regards
CB

Easiest way for ubuntu is to just put that command into /etc/rc.local and make sure it's executable.

Thank you, your suggestion works very well.

But ideally, shouldn't this option be set when the module
is loaded?

If so, how should this be done? (Can this be done with
modprobe?)

It *should* be a module option, but when I looked I was unable to see it. Have a look at the output of "modinfo ipw3945". If there was a module parameter to set it you'd expect it to be there.
